SPECIFICATION forming part of Letters iPatent No. 396,960, dated January 29, 1889.

Application filed October 15, 1888. Serial No. 288,132 (No model.)

To aZZ whom it may concern.-

Be it known that I, HORACE F. SIsE, of New York, in. the county of New York and. State of New York, have invented a new Improvementin Padlocks; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side View showing the shackle in the closed position; Fig. 2, the same view showing the shackle in the open position; Fig. 3, a top view of the shackle illustrating the hinge.

This invention relates to an improvement in that class of padlocks in whicha U-shaped shackle is hinged by one end to the case at one side, and so that the other end will enter the case upon the opposite side and be engaged by the lock mechanism.

In the use of this class of locks a dilticulty is experienced in not being able to always Open the shackle to a su'liicient extent to permit the introductimi of the thing to which it is desired to apply the lock, and this is particularly the case where the shackle is more'ot' a C shape to give a large opening through the shackle in a comparatively small case, such as shown in the illustration.

The object of my invention is to construct the shackle so that it may be opened to the full capacity. To that end the invention consists in constructing the shackle in two parts hinged together, the one part hinged to the case by one end, the free end of the other part adapted to engage the lock mechanism, in the usual manner of padlock-shackles, but so that when opened the hinged part may be turned away from the stationary part, and thus open the shackle 10 its full capacity.

A represents the case of the lock,which may be any of the usual constructions, and the mechanism within the lock may also be of any of the common constructions.

B 0 represent the two parts of the shackle. The one part, B, is hinged by one end directly to the case, as at a, and as in the usual manner for hinging shackles to padlocks. The other part, is hinged to the part Fl so as to swing on the hingein the plane of the shackle, as indicated in lnrok en lines. The free end of the part C is constructed to engage themechanism ot' the lock, as in any of the usual constructions of this class of padlocks.

To apply the lock, the shackle is disengaged and thrown backward, as seen in Fig. 2, to its extreme position. It will be observed that the opening between the free end of the shackle and the case is very much less than the capacity of or space within the shackle, and so that only a narrow opening into the shackle is produced for the a )plication of the look; but by swinging the hinged part (1 upon its hinge, as indicated in broken lines, 2, the shackle is opened to its full capacity, and made capable of embracing anything not greater than the space between the shackle and the case when in the closed position. Fnder this construction I am enabled to make the shackle of more nearly a circular shape, so as to present a large opening through the shackle, but yet bring the two ends of the shackle in the closed position so near together thatasmaller case may be employed with such a shackle than could be employed with a shackle of common construction, which presented an equalsized opening between the shackle and the casethat is to say, under the common construction, it the shackle have an equal capacity, as the shackle in this case, the two ends must be so far apart that when opened the full capacity of the shackle will be present-ed, and the case must be of corresponding size.

I claim In a padlock, a shackle made in two parts, one part hinged by one end to the case, and the second part hinged to the other end of the said one part, so as to swin in the plane of the shackle, the free end of the said second part constructed to engage the mechanism of the lock, substantially as described.

HORACE F. SISE.
